Description (CNA)
In the Linux kernel, the following vulnerability has been resolved: ceph: avoid putting the realm twice when decoding snaps fails When decoding the snaps fails it maybe leaving the 'first_realm' and 'realm' pointing to the same snaprealm memory. And then it'll put it twice and could cause random use-after-free, BUG_ON, etc issues.
